About IPNI

The International Plant Names Index (IPNI) is a database of the names and associated basic bibliographical details of all seed plants. Its goal is to eliminate the need for repeated reference to primary sources for basic bibliographic information about plant names. The data are freely available and are gradually being standardized and checked. IPNI will be a dynamic resource, depending on direct contributions by all members of the botanical community.

IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew, The Harvard University Herbaria, and the Australian National Herbarium


News: IPNI Logs its 100,000th Query

Since the soft launch in mid-December 1999 hit rates to the International Plant Names Index have been rising and the 100,000th query was logged on May 25 2000.

Meanwhile we have been working hard to improve the quality and quantity of the data available - the latest data set just released includes additional records for recently published names recorded until 23rd May 2000, as well as much data on geography and basionyms not previously available in this form.

This port of the data uses immutable IDs for the names, which will make stable links to IPNI possible for other institutions. If you would like to link your web site or database to IPNI then find out more here
